Variable Review Help

[Crichter141]

We created a variable but when we preview it in the application we're getting a missing ')' error.   When I take out the CHR(39) in Qlik the coding is fine, but that has worked in other variables.  Can anyone spot what I'm doing wrong?

Thanks in advance!

LET vPYMinCurrentDateSelection = '=
if(GetFieldSelections([DATE FILTER GROUPS]) = '&CHR(39)&'TODAY'&CHR(39)&', $'&'(var_12MonthsAgo),
if(GetFieldSelections([DATE FILTER GROUPS]) = '&CHR(39)&'CURRENT SEASON'&CHR(39)&', $'&'(var_2_Season_Ago_Start_Date),
